This sounds great for the gregarious types of people who can keep up a conversation for hours at a time, in exactly the same way that a multi-pitch overnight rock climb would be great for people with the skill and the physical fitness to do that climb. The problem I have with these type of articles is that they make these types of activities seem more accessible than they actually are. If you dissect this “walk and talk” activity it becomes clear that this is every bit as exclusionary as any high-performance endeavor (e.g. a 100km per day week long bike ride, or triathlon). Yes most people can walk, but how many people can walk and participate in 10 hours of conversation a day for 7 days? I’m glad this exists, and that these folks have the passion, so that the segment of the population up for this can have these experiences.
